Resumo(s): | Biological agents on building materials can be considered a widespread occurrence that can promote changes in stone surfaces, namely, outdoors, which are frequently considered undesirable. As with many other issues, there have been proposals of nanoproducts for treatments against biological growths. In this chapter, results of tests with nanoproducts on natural stone and other porous inorganic materials that have data on the actual effect on biocoatings (e.g., bacteria, fungi, and algae) are discussed, considering also the impacts on the materials. The collected data showed mixed results, especially for intensive water conditions (e.g., dripping, sprinkling, runoff, and immersion), namely, in relation to algae. The main issues in terms of impact on the materials concern the introduction of soluble salts (that might promote stone erosion) and color changes. Discussion on questions related to the environmental impact of nanoparticles, considering their mobility after application and their effects, is also explored. |
